FIELD OF THE INVENTION

[0001] The present invention relates to a lampshade with a plating filmlayer, and especially to a lampshade with a high temperature tolerance,a user-friendly insulation, and decorative colors. Furthermore, thelampshade with a plating film layer complies to the requirement ofenvironment protection.

BACKGROUND OF THE INVENTION

[0002] With the progress of modern living style, decorating lamps aremore and more important in the human life. The lamps are used in indoordecoration to increase the lightness and beauty of the environment.Therefore, many lamps, such as wall lamps, hanging lamps, table lamps,ground lamps or track lamps are developed.

[0003] The prior art of plastic lamps has inner walls which are coatedwith a painting layer to reflecting light. As a bubble lights up, thelight is reflected by the painting layer. Such design has lower cost,and yet, it has no tolerance of high temperature and has a bad heatdissipation. Traditional lampshade is easy to crack due to hightemperature and the painting is easy to strip out, so that the lampshadeand the whole lamp have a shorter lifetime.

[0004] Therefore, it is obvious that the prior art design has defectswhich are necessary to be improved.

SUMMARY OF THE INVENTION

[0005] Accordingly, the primary object of the present invention is toprovide a lampshade with a plating film layer, wherein the color of theplating film layer can be varied and is high temperature tolerable, andhas a preferred fire-proof effect. The lampshade will not crack due tohigh temperature. The plating film layer will not strip out. Therefore,the lampshade and moreover, the whole lamp have a longer lifetime.Furthermore, the lampshade of the present invention is ceramic and thusit can be reused for meeting the requirement of environment protection.

[0006] Another object of the present invention is to provide a lampshadewith a plating film layer, wherein the lampshade is suitable for halogenlamps, light emitting diode bubbles and conventional lamps.

[0007] A further object of the present invention is to provide alampshade with a plating film layer, wherein the lampshade is made byceramics; and a plating film layer formed by a lower temperature sputterbeing installed on the lampshade. A receiving chamber is installed inthe lampshade. A receptacle is elastically supported in the receivingchamber. The inner wall of the receiving chamber has an inner thread.The inner thread and receptacle serves for inputting power so that pinsof a bubble are connected to the receptacle or threaded into the innerthread. The present invention is suitable for halogen lamps, lightemitting diode bubbles and conventional lamps.

[0008] The various objects and advantages of the present invention willbe more readily understood from the following detailed description whenread in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Referring to FIG. 1, the cross sectional view of the presentinvention is illustrated. The present invention provides a lampshadewith a plating film layer. The lampshade 10 (see FIG. 1) made byceramic, has variable shapes as desired. The inner wall of the sputter10 is installed with a plating film layer 20 manufactured by lowtemperature sputter.

[0015] Referring to FIG. 2, a schematic view of the lampshade sputteringsystem of the present invention is illustrated. In the presentinvention, a P.V.D. ion cleaning (physical sputter) and ion coating areused for coating TiN (titanium nitride), ZrN (zirconium nitride), orCrCN (chromium carbon nitride) and other elements on the lampshade 10.The sputtering system has a chamber 30. The chamber 30 has a gas outlet31 for being connected to a pump for pumping the inner part of thechamber 30 to become a vacuum chamber. The chamber 30 is furtherinstalled with a gas inlet 32 for inputting reactive gas. A work pieceframe 33 is installed within the chamber 30. The work piece frame 33 isinstalled with a plurality of work piece fixture 34. The work pieceframe 33 is rotatable for driving the lampshade 10 on the work piecefixture 34 to rotate. The chamber 30 is installed with an ion source 35and an arc source 36. The arc source 36 may emit small ions and then bythe assisting of the ion source 35, the ions from the arc source 36 arefurther ionized so as to have a preferred adhesion and be easily formedwith a multiple-element plating film layer 20 with other ions (see FIG.1). Therefore, by aforesaid structure, a lampshade 10 of the presentinvention is formed.

[0016] The inner side of the lampshade 10 is installed with a receivingchamber 11. The inner wall of the receiving chamber 11 is formed withinner thread 12. The inner thread 12 can be formed with a plating filmlayer or a copper piece, or other conductors having conductive functionby low temperature sputter for inputting proper power. The receivingchamber 11 has a receptacle 13. The receptacle 13 can be received in areceiving chamber 11 for moving forwards and backwards freely. A spring14 is installed in a the receiving chamber 11 for elastically supportingthe receptacle 13 in the receiving chamber 11. The front end of thereceiving chamber 11 is installed with a stop 15 for preventing thereceptacle 13 from moving out of the receiving chamber 11 as movingforwards. The receptacle 13 is installed with two inserting holes 16 andeach inserting hole 16 is installed with a copper clip 17 therein. Thecopper clip 17 is connected to a proper lead 18 for inputting properpower to the copper clip 17. Therefore, by aforesaid structure, alampshade of the present invention is assembled.

[0017] Referring to FIG. 4, the lampshade 10 of the present inventioncan be suitable for the general halogen lamp (or light emitting diode)40. The halogen lamp 40 has two pins inserted into the inserting holes16 of the receptacle 13. The two pins 14 are further clamped in the twocopper clips 17 for fixing the halogen lamp 40 so that power can betransferred to the halogen lamp 40 and then the halogen lamp 50 lightsup.

[0018] With reference to FIG. 5, the lampshade 10 of the presentinvention can be used in a conventional bubble 50. The bubble 50 resistsagainst the receptacle 13 to be reduced into the receiving chamber 11.The bubble 50 is threaded with the inner thread 12 for fixing the bubble50 so that power can be transferred to the bubble 50.

[0019] The present invention is suitable for a halogen lamp, a lightemitting diode lamp, and a conventional lamp. Therefore, the presentinvention can be used widely, and the cost in mold can be reduced andtherefore, the manufacturing cost is decreased greatly.

[0020] The zirconium and titanium used in the present invention belongsto the same family, and most properties thereof are identical totitanium, but 20 have a lower ionization energy and has a smallerparticle size and a good heat dissipation. The hardness of TiN mayachieve a value of 2400 HV and has a gold yellow color. ZrN has ahardness of 3100 HV and has a gold green color. The CrCN has a hardnessof 2400 HV and has a gold color.

[0021] In the present invention, the ion sputtered coating in the PVDvacuum may be formed with a plating film layer 20 with a uniform coatingand has a lower coating temperature without any thermal deformation andany thermal stress. The ceramic material can retain the originalphysical nature. The thickness of the film is controllable by sputtertiming.

[0022] The PVD (physical sputter) used in the present invention is alower temperature process (120 degree C. to 380 degree C.). As thelampshade is coated with various elements, it has a preferred adhesion,a high hardness and a high density. The plating film layer 20 isinstalled within the lampshade 10, and thus a good reflectivity isprovided. When the bubble lights up, the light can be reflected throughthe plating film layer 20. The lampshade of the present invention ismade by ceramics and has a plating film layer 20 with a preferredinsulation and being insulated. The color of the plating film layer 20can be varied and is high temperature tolerable, and has a preferredfireproof nature. The lampshade will not crack due to high temperature.The plating film layer 20 will not strip out. Therefore, the lampshadeand moreover, the whole lamp have a longer lifetime. Furthermore, thelampshade 10 of the present invention is made by ceramics and thus itcan be reused for meeting the environmental requirement.

[0023] Furthermore, referring to FIG. 3, other than being installed atthe inner wall of the lampshade 10, the plating film layer 20 formed byPVD vacuum ion sputter coating may be formed on the outer wall of thelampshade 10 for enhancing the outlook of the lampshade to be moredecorative.
